"Sri Lankan girls!" joke

If you kiss her, you are not a gentleman
If you don't, you are not a man
If you praise her, she thinks you are lying
If you don't, you are good for nothing
If you agree to all her likes, you are a wimp
If you don't, you are not understanding
If you visit her often, she thinks it is boring
If you don't, she accuses you of double-crossing
If you are well dressed, she says you are a playboy
If you don't, you are a dull boy
If you are jealous, she says it's bad
If you don't, she thinks you do not love her
If you attempt a romance, she says you didn't respect her
If you don't, she thinks you do not like her
If you are a minute late, she complains it's hard to wait
If she is late, she says that's a girl's way
If you visit another woman, you're not putting in "quality time"
If she is visited by another man, "oh it's natural, we are girls"
If you kiss her once in a while, she professes you are cold
If you kiss her often, she yells that you are taking advantage
If you fail to help her in crossing the street, you lack ethics
If you do, she thinks it's just one of men's tactics for seduction
If you stare at another woman, she accuses you of flirting
If she is stared by other men, she says that they are just admiring
If you talk, she wants you to listen
If you listen, she wants you to talk

Unexplained phenomena:
Sri Lankan girls have this thing for jokes. However,
once you tell them a little a joke that, let's say,
rated' R', they have this thing where first their
sense of humor strikes, and therefore they find it
funny, and laugh.
But they soon recover, and then start blaming the guy
for telling nasty joke.
My question is, IF it is nasty, why do you laugh in
the first place...???
Unexplained phenomena.

WARNING...!!
While most Americans might find this to be rather strange, DO NOT, I REPEAT, DO NOT, ever in your life, call a Sri Lankan girl a woman.... Oh no, you're gonna regret it...
